Dear Sir,
If I take the liberty to trouble you with these lines, I must in the first instance rely solely on the great kindness with which you received me during your last short stay in Paris in the late autumn of last year, when Herr Schlesinger casually introduced me to you. There is, however, still another circumstance which encourages me to this step: My friend Heinrich Laube, the author, wrote to me last summer from Carlsbad that he had there made the acquaintance of one of your countrymen, who boasted of being your friend; that he had spoken to that gentleman of me and my plans, and engaged his interest in me to such an extent that he (the gentleman) of his own accord promised to introduce me to you, as he was on the point of starting for another watering-place, where he would be sure to meet you.
You observe, dear sir, with what remote and uncertain contingencies I am obliged to connect my great hope; you observe how anxiously I cling to feeble possibilities to attain a priceless boon. Was that promise ever fulfilled, and could it have been? My eternally unlucky star almost forbids me to believe it. The question, however, I owed to myself, and all I ask for at present is the honour of a Yes or a No!
